No, they are not. Jeff Cody had a patch series that converted
qemu-iotests/check to run every test in its own subdirectory instead of
in a shared spot, which we would have to revive first.

I like it; it gives me an idea of how long a test is expected to run
(some are definitely longer than others), and whether the 'quick' tag is
appropriate. But I will not necessarily be heartbroken if you can't
preserve it while making the test output easier to consume by other tooling.
